I am getting class cast exception when trying to setup micro gateway in APIM 2.6.0. please advise.
please advise.
command executed : ./bin/micro-gw setup hello-world -a HelloWorld -v v1
[2021-01-06 15:19:21,126] DEBUG {org.wso2.apimgt.gateway.cli.rest.RESTAPIServiceImpl} - Retrieving API with name HelloWorld, version v1 was successful.

In this example, I had selected API that had Tier value selected as bandwidth based throttling. I have removed that and re-published this API to resolve issue. It worked after that. I do not need bandwidth based throttling right now, if someone need that then this issue will be there.Thanks

I'm trying to use GCP Data Fusion Basic Edition with Private IP option, buth when I try to create a pipeline every action gives me this error
No discoverable found for request POST /v3/namespaces/system/apps/pipeline/services/studio/methods/v1/contexts/default/validations/stage HTTP/1.1
any suggestion on how to solve this issue
Thanks
This error is indicative of Pipeline Studio service being down. Check the status of Pipeline Studio in System Admin and look at the logs as described here.
You can restart the pipeline studio service by going to System Admin > Configuration > Make HTTP Call.
Change the method to POST and set path to namespaces/system/apps/pipeline/services/studio/start
You can validate your pipeline once pipeline studio status becomes green.
We have 2 React Native app are using AWS Cognito for authentication. We use library react-native-aws-cognito-js in our code. The apps are working fine until these 2 days. Apps are experiencing intermittent "Internal Server Error".
How can I find more information about this error? Any tool can help us pinpoint the cause?
Update
From CloudTrail, each API call has an event "CreateNetworkInterface". Many of such API calls have error code "Client.NetworkInterfaceLimitExceeded". What is the cause and solution to this?
According to this AWS Doc (in Chinese), CloudWatch will not write to log when error is due to insufficient IP/ENI. That explains the increase in error number but no logs in CloudWatch.
Upate 2
We have found a scheduled Lambda job which may exhausted IP addresses. We stopped the batch job. But still can't have too many user login to server due to "Client.NetworkInterfaceLimitExceeded" error. I realized that there are many "CreateNetworkInterface" event and few "DeleteNetworkInterface" event. How can I "clean up / reset" all network interface in VPC?
Short answer: Cloud Trail.
Long answer with a suggestion
Assuming your application code is fine, most likely the cause of your 500 error is based on Cognito's initial limitations (e.g., number of calls per user): https://docs.aws.amazon.com/cognito/latest/developerguide/limits.html.
AWS suggests to use Cloud Trail, for logging Api calls.
However I would suggest, to prove the limitations first, add some logs around the api call yourself, and in development you could call your app/api with a high number of calls; and most likely you will see the 500 error due to the limitations.
You could do the following in the terminal:
for i in `seq 1 1000`; do curl --cookie SecureCookie=TokenValueFromAWS http://localhost:desirablePort/SecuredPath; done
I configured an ESB cluster following this documentation
https://docs.wso2.com/display/ESB500/Clustered+Deployment but I still got a problem.
In each ESB nodes I got this log
WARN - CarbonEventManagementService CEP started with clustering enabled, but SingleNode configuration given.
instead of this one
INFO - RpcMembershipRequestHandler Received JOIN message from
Is there a way to have more details on the log to get what is wrong ?
I can post configuration files if someone can help ^^
Thanks !
If you are using hostnames for localMemberHost and <member> section in axis2.xml, change them to use IPs instead.
after running AWS Elastic Beanstalk application for few weeks suddenly I can't open my application. Page simply displays an error which doesn't provide much information how to fix it.
Error
A problem occurred while loading your page: AWS Query failed to deserialize response
(and there is no more information, Googling also haven't found any answer)
So before updating my subscription and starting paying to Amazon not insignificant amount of money for being able to contact their technical support I thought I will ask here first if someone here encountered this issue.
Thanks for any suggestions.
After receiving this generic error, I was able to dig into the actual error message by using the EB CLI. In my case the CLI threw "ZIP does not support timestamps before 1980".
I get the following error:Service Invocation Exeption i am working with Version 8.7 IBM InfoSphere DataStage and QualityStage Designer and using a server job and there, i have 1 sequential file, web service, sequential file.
Any idea what could be the reason of this error ?
Make sure you have chosen proper DataStage job type and your stage that operates on web service is configured properly.
You should also check the DataStage logs to get more information about root cause of the error.
